Question

The density of water is 1.0 g/cm3. The density of the oil in the left column of the U-tube is

Answer 1

23.52 is the answer.

Answer 2

Answer:

The density of oil in the left column of the u-tube will be between 0.7 to 0.9 gcm⁻³.

Explanation:

• We know that the density is given by mass per unit volume. So, density of a substance depend upon its mass. If the mass is greater than density will be higher. Because oils are less denser, therefore they have less density.
• The density of oil depends upon the composition of oil molecules present in it. Water is more denser than oils. So when we mix water and oil together. the oil will form upper layer over water. Now we know that density of water is 1.0gcm⁻³. Therefore, the density of oil will be less than the density of water. So, it could be between 0.7 to 0.9 gcm⁻³.
